Area shaded = Area big circle- Area of small circle;
200 pi= pi•(2x)^2 -pi•6^2;
200pi= pi•4x^2 -pi•36;
200pi=pi•4(x^2 -9) divide both sides by 4pi;
50=x^2 -9; So x=sqrt(59)~7.68cm
Answer:
13% per pair of shoes
because if she 78% on 6 shoes you would divide 78 by 6 to find the percent she spent on one pair of shoes
In terms of its radius 
, the volume of the balloon is
The diameter 
is twice the radius, so that in terms of its diameters, the balloon's volume is given by
Differentiate both sides with respect to time 
:
The diameter increases at a rate of 
. When the diameter is 
, we have
or about 23,562 cc/min (where cc = cubic centimeters)
Answer:
Rounded, 22 yards.
Step-by-step explanation:
The pythagorean theorem states: a^2 + b^2 = c^2
a = 34, squared = 1156
b = 41, squared = 1681
Add those to get 2837.
√2837 = 53.26, rounded.
34 + 41 = 75
75 - 53 = 22
22 yards is your answer.
